a r t i c l e i n f o We examine the role of agricultural productivity as a determinant of China's post-reform economic growth and sectoral reallocation. Using microeconomic farm-level data, and treating labor as a highly differentiated input, we find that the labor input in agriculture decreased by 5% annually and agricultural TFP grew by 6.5%. Using a(More)
PNAS-4, a novel pro-apoptotic gene, was activated during the early response to DNA damage. Previous studies have shown that hPNAS-4 can inhibit tumor growth when over-expressed in ovarian cancer cells. However, the underlying action mechanism remains elusive. In this work, we found that hPNAS-4 expression was significantly increased in SKOV3 cells when(More)
Ovarian cancer is the number one cause of death from gynecologic malignancy. A defective p53 pathway is a hallmark of ovarian carcinoma. The p53 mutation correlates significantly with resistance to platinum-based chemotherapy, early relapse and shortened overall survival in ovarian cancer patients. PUMA (p53 upregulated modulator of apoptosis), a BH3-only(More)
OBJECTIVE We aimed to investigate the role of the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway and its negative feedback factor, phosphatase and tensin homolog (PTEN), in the pathogenesis of Crohn's disease (CD). METHODS Peripheral blood was collected from patients with CD and healthy(More)
Ovarian cancer is the most common cause of death from gynecologic malignancy. Deregulation of p53 and/or p73-associated apoptotic pathways contribute to the platinum-based resistance in ovarian cancer. NOXA, a pro-apoptotic BH3-only protein, is identified as a transcription target of p53 and/or p73. In this study, we found that genetic variants of Bcl-2(More)
A label-free and selective aptamer beacon-based Love-wave biosensing device was developed for prostate specific antigen (PSA) detection. The device consists of the following parts: LiTaO3 substrate with SiO2 film as wave guide layer, two set of inter-digital transducers (IDT), gold film for immobilization of the biorecongniton layer and a(More)
Noxa is an important proapoptotic protein in the intrinsic pathway of cell apoptosis. Experiments were carried out to investigate whether Noxa could, therefore, enhance the cytotoxic effect of gemcitabine in human ovarian cancer cell lines (A2780 and COC1). In this study, the combined treatment of Noxa and gemcitabine, in vitro, significantly inhibited the(More)
Secondary pneumonia due to Staphylococcus aureus (S. aureus) causes significant morbidity and mortality. The aim of the research was designed a novel DNA vaccine encoding the Mycobacterium tuberculosis secreted antigen Ag85A fused with the influenza A virus (IAV) HA2 protein to provide protection against both influenza and secondary infection with S.(More)
OBJECTIVE The purpose of this study was to observe the apoptosis of A2780 cells transfected with the recombinant plasmid of pcDNA-Bax and to observe the release of cytochrome C from the mitochondria. METHODS The recombinant plasmid of pcDNA-Bax was constructed and transfected into A2784 cells. The Hoechst 33258 stain method was applied to evaluate the(More)
According to the requirement of collaborative product development in military industry academy and subordinate institutes, a solution of collaborative development platform based on the PDM is proposed. The solution can integrate heterogeneous PDM systems in academy and subordinate institutes to achieve transverse interconnect and vertical exchange. This(More)
